Lol no, you are making it bigger deal than it is with cards or stuff like that imo. We are not deaf, we can communite with voice and mouth. If it is a long conversation, we can say "btw i have stutter" is more than enough. I am living in a sh*t show middle east country, i can't remember the last moment I need to explain that i've stutter. People of course notice it with my early sentences and they just keep conversation normally. Some people asking something like "did you ever tried treatment" or saying "my nephew had that and he cured himself by reading book" bla bla. Actually I dont want to carry or put a card to my chest to block some questions which is only %5 of people asking. Btw i have a job which is require to speak a lot with different people.
